## Description

We're looking for a Senior Full-Stack Engineer to lead the technical execution of Plaud's transition from Shopify Liquid to a headless commerce stack. This is the foundational engineering role for Plaud's e-commerce platform for the future. You will treat the website as a long-lived product platform - not a one-shot rebuild.

What you will do

 * Architecture & Code Quality
 + Design and lead the Hydrogen + Shopify Storefront API + Contentful architecture
 + Set patterns for multi-locale routing (plaud.ai/[lang-country]), data fetching, caching, edge runtime
 + Define and enforce performance budgets (LCP < 2.0s, INP < 200ms, CLS < 0.1)
 + Lead CI/CD, preview deploys, observability, and code review standards
 * Migration Execution
 + Own phase-by-phase migration: non-commerce pages PDP Collection Checkout Multi-region
 + Drive technical decisions on App migrations (Klaviyo SDK, Refersion/Impact, Yotpo, Algolia)
 + Ensure 95%+ Ads pixel parity in dual-tracking phase
 + Coordinate redirect mapping and SEO-safe URL migration
 * Cross-Functional Leadership
 + Partner with Marketing (Performance + Lifecycle), SEO, Finance, Logistics, and Partnership teams
 + Translate business requirements into engineering work; defend engineering bandwidth from scope creep
 + Own the technical narrative for cross-functional decision gates (M0-M11)
 * Team Leadership
 + Recruit and mentor 2 junior engineers; embed AI-augmented development (Claude Code / Cursor / Copilot) as default
 + Establish and enforce quality bars (testing, A11y, performance)
 + Drive engineering culture: ownership, ship velocity, blameless postmortems
